there is generally three types of delivery. 

1. by sea

When the cargo is very much and quite heavy , we  ship cargo by containers or combined container.

2 by cargo air 

If the cargo is light (eg, 50-200kg) , we could ship it by air . 

3, by express such  as DHL , UPS , TNT FEX, EMS etc

If all cargo is very light , such as only (1 KG- to 50KG) , you could ship by express, thus it would be cheapest way.
